FIELD COIL BOBBIN ENCLOSING ONEESHOT PROTECTIVE BODY FOR HEAT SENSOR

摘要

A bobbin for carrying a field coil winding is made of molded plastic resin material having good electrical insulating characteristics and having an insulating channel formed in the hollow spindle portion thereof for carrying a fuse type or one-shot thermal protector. The bobbin flanges are thickened at either end of the insulating channel and sockets are formed in the flange thickened portion for carrying a quick-connect device which is generally U-shaped with slots in the legs adapted to engage coil end-wires when the device is forced into a socket. One end of the device carries a bent-over tongue adapted for locking engagement with the stripped end of an insulated lead-wire. The other end of the device carries a V-shaped camming notch contiguous with and connected to a hole adapted to admit a projecting boss formed at the bottom of each socket for forcing the terminal ends of the one-shot thermal protector carried in the bobbin insulating channel into contact with the sides of the leg slots, the socket walls being slotted for admitting the terminal ends to the sockets.
